Creating Box and Whisker Chart
A box and whisker chart is used to examine a given set of data and draw the statistical conclusion using the five-number summary principle.
In this section, you will be shown how you can:
-
Create a simple box and whisker chart
-
Use legends in the box and whisker chart
Creating a Simple Box and Whisker Chart
As an example, we will create a box and whisker chart that shows the gender-wise distribution of annual salaries.
The box and whisker chart thus created looke like this:
{
"chart": {
"caption": "Distribution of annual salaries",
"subCaption": "By Gender",
"xAxisName": "Pay Grades",
"YAxisName": "Salaries (In USD)",
